:目的　探讨被覆食管支架在食管良恶性狭窄中的应用。方法　 2 0例食管恶性狭窄和 4例良性狭窄患者 ,于X线监视下 ,经口植入被覆食管支架 ,观察临床效果及并发症。结果　放置支架后患者吞咽困难改善 ,吞咽程度由术前平均 3级降至 1级 ,所有患者皆能进普食或软食。 4例有食管 -支气管瘘者术后瘘口闭合。术后 1例发生支架移位 (Z型支架 ) ,1例食物嵌塞。随访 3～ 36个月 (平均 14个月 ) ,18例健在 ,支架均保持通畅。结论　被覆食管支架放置操作简单、安全 ,是食管良恶性狭窄及食管 -支气管瘘的有效治疗方法 Objective To investigate the application of esophageal stent in esophageal benign and malignant stenosis. Methods Twenty patients with malignant esophageal stenosis and 4 patients with benign stenosis were enrolled in esophageal stent under X-ray monitoring. The clinical effects and complications were observed. Results After stent placement, dysphagia improved and the degree of swallowing decreased from grade 3 to grade 1 before surgery. All patients were able to eat regular or soft diet. Four cases of esophageal - bronchial fistula postoperative fistula closure. Postoperative one case of stent displacement (Z stent), 1 case of food impaction. All the patients were followed up for 3 to 36 months (average 14 months), and 18 patients were alive. Conclusion The placement of esophageal stent is easy and safe to place and it is an effective treatment for benign and malignant esophageal stenosis and esophageal-bronchial fistula
